" 6 claims".v l(c1.f1"cf166` l' Y frame and.v 2r denotes a doortheedge faces #of I This invention relates to improvements .in

hinges, and refers particularly to hinges of the concealed type. This inventionk aimsgr' among otherthings, to providea hinge consisting ofl angle-shaped hinge plateszwhich can be quickly and cheaply completed in a punch press, and

likswhich can be justas readily fabricated also in: a press, in addition to which only pins and washers are employed which are made in autoe.l

` matic machines, v and subsequently the entire hinge assembled ina press. Thus I aim to pro,-`

' vide a hinge in the manufacture and assembly of which only the quickest, cheapestand simplest i operations arel performed, and the more -eX- a nated.

pensive forms of machining completely elimifl Another object of the invention is to `provide a hinge'wherein one pairof angle-shapedv hinge plates. is mounted upon a door frame and another pair of angle-shaped hinge plates upon a door, wherein two sets of spaced links are pivoted to` gether, and wherein .a pin extendsthrough each set of links and its `extremities travel in opposed slots formed inone pair of.vr hinge plates as: the door is opened andclosed. 4

' .A further object ofy theinvention is to provide sucha hinge wherein a pivot pinis atight fit through oneset of vlinks and bosses formed there-- on, and one of the other set of links is mounted for pivotal movement upon eachboss.

Yetanother object of the invention isto provide such a hinge with means holding each set ofv links in parallel and spaced relation lone with another throughout their entire length, to afford clearance .between eachadjacent pair of links of one setfor movement of one link of the other set.

Having vthus briefly and broadly stated some of the major objectsand advantages of the invention I will 'now proceed todescribe it in dethe links mounted between the hinge platessecured to the door for rsliding movement.

Referring tothe drawing, I designates a door other. f

which are recessed at 3 kand 4 respectively. Mountedas by screws aupon the door frame lI are' two vangle-shaped hinge plates' 5 having legs .6 .which extend rearwardly" inithe recess 3, andv which maybe held in spacedrelation as by. dowels- 1. "Formed inthe legs 6 'arefaligned slots-8.

Similarly upon the door 2 two kangle-shaped hinge'l '4 I' plates 9 are secured as-'by screws 9a and have-- legs I0 which-extend into'thelrecess- 4.v .These legs-may beheld inspaced relation by a vdowel II, and formed-.inthe said? legs are'aligned 'A slots I2. i -It `will benotedfrom the drawingv that each opposed pair of slots 8 and I2 are differently curved inorder to provide'the vdesired path of movementfor thedoor as the latter is openxl-andV closed.`

All the links I5 Aare identical and each has a plurality of bossesIII-'l and l'formed on one .andjthesame side thereof.. 'Through thelinks and their. bosses I6, I1,'and'.I8 openings I 6m!! 'la and I8a respectively areprovided. 1 Through Athe openings I6a a 'guides pin I9 extends, 'the ex tremities of which are slidable in thetwoialigned slots 8'; throughthev openings I'Ia'a pivot pin -2l) extends; and throughthe openings IBa a retaining pin 2| is' provided. Thelpin 2li is of substantially the samelengthlas the sum total 'of thewidth of the links I51ahdthe bosses thereon through which thatpinprojectslwhereas the eX- tremities ofthe pin u2I extend into theoppos'ed legs I0. `All the pins I-9`,-`20 and 2| -are a press 'flt through the' links thereby 1 holding the latterk in correct'spacedr and parallel'relation toonefanf;

- Asecond set of links A22 is provided. Each link has bosses 23 and 25 on one and the same side,

thereof. Through the links and their bosses 23 and 25 openings 23a and 25a respectively are formed. Each link 22y is also provided` with an v opening 24 through which one of the bosses Il extends so that each link 22 is pivoted on the boss I1 of one link-SI5.. Through the openings 23a'a guide pin 26 projects the ends of which are .each

slidable in one sTot I2; and through the openings n 25a.a retaining pin 21is arranged which is sub v n stantially the same length as the sum total ofv the'thickness of all; the links 22 and the depth` of their bosses 25 plus the thickness of thelegs 6 in which the extremities of thel said piny 2l terminate. In this case too the pins 26 Vand yZ'I are v p a tight t in the links 22 through which'they exy tend thereby holding. the severallinks in spaced@ and parallel relation. l

The faces of all the bosses I6, I 'I and I8, and

23 and 25 which rest contiguous to the legs 6 and Ill of the hinge plates 5 and 9 respectively are of substantially the same thickness as the link 22 or I5 for which these bosses provide clearance. Thus one outer link of each set moves in contact with one aligned pair of legs 6 and I0 against which it is retained by the adjacent link I5 or 22 of the other set of links, thereby supporting that outer link against movement otherrthan in one plane. `l-Iowever the spacing between adjacent links of the same set between which a link of the other set moves should be somewhat greater than the thickness of the latter link to permit freedom of movement for the said latter link and i to prevent a binding condition between the links.Y

As it is obviously advantageous from a manufacturing standpoint to make all the bosses on all the links the same thickness I provide wash# ers 3B around all the pins. One washer 3D vrests against each boss IE, II, I8, 23 and 25 which would otherwise bear against an adjacent link of the same set.

In the arrangement shown the length of the slots 8 and I2 controls the movement of the hinge though this length of movement may be controlled in other ways if desired.

While in the foregoing the preferred embodiment of the invention has been described and shown, it is understood that it issusceptible to such alterations and modifications as fall within the scope of the appended claims.

What I claim is:

1. A hinge comprising hinge plateshaving opposed legs in which alignedslots are formed, two sets of links arranged alternately one `link of one set upon one link of the other set,'bosses formed,

on one side of each link of one set upon each of which one link of the other set is pivoted, a pivot pin extending 'through all said links and said bosses, a guide pin extending through each set of links having its extremities slidable in two of the slots, and means holding each set of links in spaced and parallel relation throughout their entire length.

2. A hinge comprising two pair of angle-shaped hinge p-lates, said plates being arranged in opposed pairs, one pair adapted to be mounted upon a door frame and the other pair upon a door, one leg of each hinge plate being slotted, the slots in each pair of plates being opposite one another, two sets of links, all the links of each set being identical, a boss formed onV one side of each link ofone set upon which one link of the other set is pivoted, a pivot pin extending through all said links and bosses, a guide pin extending through all the links of each set having its extremities slidable in one pair of opposite slots, and other bosses on said links contacting other links of the same set to hold each set of links in parallel and spaced relation to permit free movement of the links of one set between adjacent pairs of links of the other set.

3. In a hinge, the combination set forth in claim 2 wherein a washer is provided between each adjacent pair of bosses.

4. A hinge comprising two sets of hinge plates,

, one set of plates being adapted to be mounted upon a door frame and the other upon a door, each set of hinge plates having two opposite slots formed therein, two sets of links, a plurality of bosses upon one and the same side of each link of both sets, said bosses spacing the links of each set from one another, each link of one set being pivoted up'on one boss of a link of the other set, a pivot pin extending through all the `links and the pivot bosses, a guide pin extending through all the links of each set and through a boss on each link of its set, each pin having its extremities slidable in one opposite pair of slots, and a retaining pin extending through al1 the links of each set and through a boss on eachlink of `its set, each retaining pin terminating at its extremities in one of the hinge plates.

5. A hinge comprising two hinge plates each having an opposed pair of legsin which slots are formed, two alternately arranged sets of links, a guide pin extending through each set and having its extremities slidable in the slots formed in one opposed pair of legs, means around :said guide ,pins retaining the links in correct spaced relation,

both sets of links being apertured for the passage of a pivot pin therethrough, each link of one set having a boss thereon upon which one link of the other set is pivoted, whereby the pivot pin is tight in one set of links and the links of the other set are freely rotatablel around the bosses on the rst set, a retaining pin through each set of links the extremities of which extend into the opposed pair of legs other than the pair in which the guide pin extending through that set of links is slidable, and means around each retaining pin holding the links through. which it passes in spaced relation.`

6. In a hinge, the combination set forth in claim 5, wherein each opposed pair of slots in which the guide pins travel is diierently curved to provide the desired path of movement for the hinge. n
